Photo Of UFO Over US Marine Base

On the night of 9/17/2011, around 9:52 pm, I was sitting in the back yard of a friends house with them. (There were 4 of us that witnessed the event) My male friend and were sitting on the couch talking and facing north. It was a clear night, no clouds. This allowed for a clear view of Joshua Tree valley over to the top of the hill on the north side. There was no air traffic in the area. I noticed a light come into view to my left at about a 45 degree angle from the bottom of this valley. The valley is maybe 2 miles across from where we were sitting to the top of the north side hill. I didnt know what ti was at first then I jumped to my feet and exclaimed, “Look! Here we go!” The others immediatly saw the object as I pointed to it. We were unable to miss it. The object was traveling west to east over the north side of the valley. The object at first had a glowing flame like aura around a white center. By the time the object got to the point of being straight in front of us, it no longer glowed red and appeared as a bright white circular disk. By then we had our camera phones out and 2 of us were taking pictures of it. There was no sound from it through the entire event. When it reached 3/4 across the valley from west to east, it dipped down then changed directions heading to the north east and dissapeared out over the 29 Palms Marine base. As a guess, the object was traveling at approximately 30 to 40 miles per hour while it was on its west to east trajectory. After 30 minutes to an hour, I noticed normal aircraft in their normal flight patterns to the north and very high up. I was extremely excited to witness such a blatant event. I remained excited the rest of the night and continued to watch the skies in the area on and of till I went to bed without any further sightings.
